Probing the vacuum as a chiral medium

T. Heinzl, B. King, A. Mercuri-Baron

We study the circular birefringence experienced by linearly polarised photons colliding with a circularly polarised background creating a vacuum of definite chirality (handedness).…

Coherent enhancement of QED cross-sections in electromagnetic backgrounds

T. Heinzl, B. King, D. Liu

We introduce form factors that relate the amplitude of a QED process in vacuum to its corresponding background-field process. The latter is characterised by a reduced S-matrix elem…

Letter of Intent: Towards a Vacuum Birefringence Experiment at the Helmholtz International Beamline for Extreme Fields

N. Ahmadiniaz, C. Bähtz, A. Benediktovitch +49

Quantum field theory predicts a nonlinear response of the vacuum to strong electromagnetic fields of macroscopic extent. This fundamental tenet has remained experimentally challeng…

Technical Design Report for the LUXE Experiment

H. Abramowicz, M. Almanza Soto, M. Altarelli +131

This Technical Design Report presents a detailed description of all aspects of the LUXE (Laser Und XFEL Experiment), an experiment that will combine the high-quality and high-energ…

Strong field vacuum birefringence in plane wave pulses

B. King, T. Heinzl, T. G. Blackburn

By combining an adiabatic approach based on a `locally monochromatic' approximation with a local Hilbert transform, it is demonstrated how vacuum birefringence in the strong field…

Strong-field vacuum polarisation with high energy lasers

A. J. Macleod, J. P. Edwards, T. Heinzl +2

When photons propagate in vacuum they may fluctuate into matter pairs thus allowing the vacuum to be polarised. This linear effect leads to charge screening and renormalisation. Wh…
